Basically LCMinutes is an application that keeps track of phone calls, SMS, and data traffic, calculates their charge based on user defined rate plan, and thus keep user informed of the up-to-date balance information: like current charges, used free minutes, used free messages, used free data allowlance, expire date for prepaid plans, etc.

Changes:

* Feature change: Add more traces for day and month change.
* Bug fix: change free minutes or data allowance is not updated to balance info when user choose to apply new rate plan to existing usage.
* Bug fix: +/- sign in special rates not handled correctly.
